This study identifies the most common biological concepts presented in elementary science textbooks in Taiwan. The concepts focus on living things, animals, and plants in grades one through four. Three major areas of concern are: attributes of the three related concepts; development of the concepts focusing on content organization and their connections, repetition, and complexity; and pedagogical emphasis of the text. The commonly addressed attributes were found to be "habitat,""movement,""growth,""energy source," and "structure." Concepts are organized from high level to low level, and links among the concepts within a unit or across units are not adequately made. The application of concepts is neglected and inquiry-based experiments are lacking. Contains 16 references, 3 data tables, and 3 figures. (Author/DDR)
